Come on, this is the kind of thing I meant. You question his priorities and judgement? Seriously? Because he shared a little project he put together? He made a thing. He shared it. That's it. It's not like he is selling this, or promoting it as some great thing. I imagine he thought other people on HN would find it interesting given all the discussion of Apple's touch bar, so he shared it. No need to be so antagonistically critical of what is obviously not a finished product. A little kindness and consideration goes a long way.
